    Staging: olpc_dcon: replace some magic numbers · 98d4f93c

    This patch replace some magic numbers. I believe it makes
    the driver more readable.
    The magic number 0x26 is the XO system embedded controller
    (EC) command 'DCON power enable/disable'.
    Number 0x41, and 0x42 are special memory controller settings
    register.  The 0x41 initialize bit sequence 0x101 means:
    enable memory power down function and special SDRAM clock
    delay for synchronize SDRAM output and clock signal.
    The 0x42 initialize squence 0x101 is wrong.  According to
    the specification Bit 8 is reserved, thus not in use.
    I removed it.
